Specification
Brand : VERIMP
BulletPoint1 : Purpose: Mainly used to demonstrate the phenomena that occur when the inductor is powered on and off in the circuit.
BulletPoint2 : Working voltage: DC 10 V for power-on self-inductance; DC4V for power-off self-inductance.
BulletPoint3 : The phenomenon of induced electromotive force in the coil due to changes in its own current is called self-induction.
BulletPoint4 : The direction of the self-induced electromotive force is: when the current increases, its direction is opposite to the current; when the current decreases, its direction is the same as the current direction.
BulletPoint5 : The demonstrator uses two inductors, a small 3.8V light bulb and a high-brightness light-emitting diode to display changes in self-induction phenomena. It has the characteristics of good reliability, intuitive and obvious experimental results, and easy operation.

Purpose: Mainly used to demonstrate the phenomena that occur when the inductor is powered on and off in the circuit. The demonstrator uses two inductors, a small 3.8V light bulb and a high-brightness light-emitting diode to display changes in self-induction phenomena. It has the characteristics of good reliability, intuitive and obvious experimental results, and easy operation. It is a must-have instrument for middle school physics teaching experiments.

Power-on self-induction phenomenon:
When the circuit is turned on, the current through the inductor winding increases, generating an induced electromotive force in the coil, which will hinder the increase in current through the winding, so the small light bulb connected in series with the inductor gradually lights up.
Self-induction phenomenon during power outage:
When the circuit is disconnected, when the induced electromotive force is generated in the coil, the voltage generated at both ends of the coil winding is the self-induction voltage. Therefore, the light-emitting diode connected reversely to the power supply voltage can shine at the moment when the small light bulb goes out.
